    Study Notes

    Hydrogen

    • Unique element not part of any group on the periodic table
    • Has 1 valence electron, making it very reactive
    • Exists as a gas at room temperature, colorless and odorless

    Alkali Metals

    • Group 1 elements with 1 valence electron
    • Characterized by a silver color and low density
    • Extremely reactive, especially with Group 17, forming a +1 charge

    Alkali Earth Metals

    • Group 2, featuring 2 valence electrons
    • Highly reactive and good conductors of electricity
    • Typically bond with Group 16 elements to achieve a +2 charge

    Transition Metals

    • Comprise Groups 3 through 12 of the periodic table
    • Conductivity increases from left to right, while reactivity tends to decrease
    • Includes the Lanthanide and Actinide series with varying valence electrons

    Boron Group

    • Group 13, named after its top element, boron
    • Consists of one metalloid and the remainder as metals
    • Contains 3 valence electrons

    Carbon Group

    • Group 14, named after carbon, the top element
    • Contains 4 valence electrons, one non-metal, two metalloids, and remaining metals

    Nitrogen Group

    • Group 15, named after nitrogen, containing 5 valence electrons
    • Consists of two non-metals, two metalloids, and one metal

    Oxygen Group

    • Group 16, named after oxygen, featuring 6 valence electrons
    • Composed of three non-metals, one metalloid, and one metal

    Halogens

    • Group 17 elements having 7 valence electrons, all of which are non-metals
    • Poor conductors of heat and electricity, highly reactive
    • Tend to bond with Group 1 to form a -1 charge

    Noble Gases

    • Group 18 elements that are inert and not reactive
    • Characterized by a full valence shell, resulting in no bonding with other elements

    Metals

    • Majority of elements fall into this class, found on the left side of the periodic table
    • Features include being shiny, good conductors, malleable, and ductile
    • Most are solid at room temperature, except mercury, which is liquid

    Nonmetals

    • Located on the right side of the periodic table, they lack malleability and ductility
    • Poor conductors of heat and electricity; about half are gases at room temperature

    Metalloids

    • Positioned along a zigzag line, exhibiting properties of both metals and nonmetals
    • Comprises 8 elements in total with mixed characteristics

    Isotope

    • Variants of an element differing in neutron count
    • Leads to atoms of the same element possessing different atomic masses

    Cation

    • A positively charged element formed when there are fewer electrons than protons

    Anion

    • A negatively charged element created when there are more electrons than protons
